slibc, the Stockholm C Library, is an implementation
of a C libray, for POSIX, just for fun.
slibc does not aim to support C++, or any other
language than C. Furthermore, it does not try
to support older versions of C than C99.
Macro definitions:
_SLIBC_SOURCE -- Enable slibc extensions. These extensions
are usually extensions introduced in other
C libraries, but are considered good extensions.
_GNU_SOURCE -- Enable glibc extensions (GNU extensions.)
_BSD_SOURCE -- Enable BSD extensions.
_SLIBC_SUPPRESS_WARNINGS -- Suppress all #warning and other warnings, this is
primarily intended to be used when compiling slibc.
_PORTABLE_SOURCE -- Unconditionally disable all extensions.
_LIBRARY_HEADER -- Alternative to _PORTABLE_SOURCE that should
be used in header files for libraryes. This
allows you to be sure that your library is
portable between libc:s, and that sources
using your library does not been to be compiled
with the same libc. It is important to use
this instead of _PORTABLE_SOURCE in library
header files, otherwise the user of the library
cannot fully utilise _PORTABLE_SOURCE.
slibc provides some slib-specific extensions that
do not require _SLIBC_SOURCE. (They are however
disabled if _PORTABLE_SOURCE is defined.) These
extensions are defined in header files whose
name starts with `slibc-`. Headers starting with
`slibc/` are not extensions, those are internals
that may change at any time.
